How long have you watched MMA: Since I was about 10 or 11, back when the guy flexing was the logo, ha. I can remember hyper little Martial Artist jumping and kicking Sumo-esque brawlers in the face.
How often do you watch it: Extremely often.
What interested you in the sport intially (an aspect of it, a fight, a fighter, etc): Ken Shamrock. Not as a WWF/E crossover, but before then. Somehow I got my hands on a fight and liked him. If not for MMA I may not have ever gotten into wrestling.
What MMA promotions you watch/have watched: UFC, WEC, Pride, K-1. Bodog, and that company that always runs shows out of Hawaii (for the life of me I can't remember the name).
First fight and/or event viewed (that you can remember): See: hyper little Martial Artist
Last fight and/or event viewed: UFC 81
Favorite fighter (that you support or just enjoy watching): Ken Shamrock, Forrest Griffin, Heath Herring, GSP
Least favorite fighter: Tito Ortiz

Favorite event: Nothing specific. I enjoy cards.
Favorite knockout: Any Liddell side-step, heavy left, knock out.
Favorite submission: GSP last fight, tapping Hughes
#1 Pound for Pound Fighter based on wins (in your opinion): Hard to say. Rampage at the moment.
